4Application filed May This invention relates to gra-in separators or lthreshers and has for an object the provision'of a machine which ymay receive the straw and grain lfrom a harvesting machine,

5 separate the grain from the straw and chaif and elevate the separatedgrain into abin or other container.

Another object of the invention is the provision of a'thresher and-separator whichinay form a part of acombine harvester.

Another object of the invention istheprovision of a combined thresher and separator having a-novel form of cylinder, in which the grain is separated lfrom the straw and chaif 5 and carriedto a suitable container `or receptaclefin arthoroughly cleaned condition.

Withthe above andother objects `in view, the invention further includesthe'following novel features-and details of construction', to

fully described, illustra-ted in the accompanying `drawings and pointed out in the appended claims.

Referring tofthedrawin'gs indetail where- ;40 in ilikeicharacters kof referencev vdenote corresponding parts, the machine as shown comprises a iframe lwhichfincludes longitudinally disposed sills 10, a casing 1l, and a cylinder 12. The cylinder is mounted for rota- 45.. tion upon flanged rollers 13, provided at opposite ends of the frame, the rollers being mounted upon longitudinally disposed shafts 14.

The cylinder includes end frames to '5.0 -which are secured the opposite ends of a 1931. semaine. 539.340.

woven wire or other foraminousmaterial 16 whichis adapted for the passage of grain. Arranged :longitudinally within the cylinder are circumferentially spaced bars 17 These bars are secured'to the end frames 15 and 55 serve to reinforceand strengthen the cylinder structure. In addition, these Abars carry spaced rearwardly and circumferentially inclined fingers 18 whose inner looped ends 19 pass through openings 20 provided in the 60' bars17. Y l Y Y Straw andv lgrain from the harvester is fed into one endof the cylinder by'means of a rotary feeder 21 lwhich is mounted Iupon a shaft^22. This feederV carries outwardlyex- 55* tending ngers 23 which pass between "iingers Y24 extending `upwardly 'from the bottom 25 of a feed trough26.4 Mounted in'bearings 27 carried-by the sills 10 isashaft28 and this shaft extends through im a housing 29 within which operate fan blades 30 whichare fast upon the shaft 28. A current of-air isthus'provided at'oneend of the cylinder -so asato carry the straw longitudinally through the cylinderv and out the oppo- 'f5 site end. Duringthe passage ofthe straw through the cylinder, arotary motion is given the -strawby theiingers 18, these'ngers suc-Y cessively engagingthe straw and due to their *rearwardr inclination,the strawwill be cars@ riedtowardthe open end` ofthe cylinder just referredito. The iingers-agitating the straw sepa-rate "the grain there-from, and the grain passesdownward andoutward through the lower portion ofthe cylinder7 while the straw 85 is carriedoutward as explained. y Y Extending longitudinally below the cylinder is a conveyor 31, the shaft 32 of which isl mounted inbearings 3,3 provided in the frame.` This conveyor yoperates within a 9@ troughlt which extends lfrom the housing v1.1 and which is in communication with a trough 35. This Vlast .mentioned trough housesl a conveyor 36,1whose :sha-ft' 37 is mounted in suitable bearings ,and carriesa sprocket 38 95 which isfdriven from a sprocket 39 by Va chain 4:0. The sprocket. 39 isimounted upon the vshaft/'.28 and/thisV shaftcarries a pulley 4l which is driven by a belt 42 from apulley't, fastaon ythe shaft 22. This last mentioned m9 pulley may be driven by a belt 44 from any suitable source of power.

The shaft 28 also passes through a fan housing 45 and has mounted thereon fan blades 46. This housing is in communication with one endof the conveyor trough 35 and has extending therefrom a vertically disposed spout 47 so that grain delivered from the cylinder will be moved by the conveyors 31 and 36 into the housing 45, and will be carried upward through the grain spout 47 into a suitable receptacle. Y

Mounted in suitable bearings and extending longitudinally along one side of the cylinder 12 is a shaft 48. This shaft extends through a cylindrical housing 49 which may be an extension of the housing 11, and mounted upon this shaft are fan blades 50.l The purpose of this fan is to provide a current of air transversely into the cylinder 12 so as to take up and separate the chaffy from the grain and arrange it in the'path-of the air from the fan blades 30 so that the chaff will be carried outward with the straw.

The shaft Q8 is geared to the lshaft 48 through the medium of worm gearing 51, while the shaft 48 has mounted thereon a sprocket /wheel 52, around which passes a chain 53. This chain engages sprocket wheels 54 which are mounted upon the shafts 14, and a sprocket wheel 55 which is mountedy upon the conveyorv shaftV 32, so that the cylinder will be rotated and the conveyor 31 operated. A tightening device 56 is provided by the chain 53 whereby the lattermay be properly tensioned. Y Y i Extending upwardly and rearwardly above the top of the cylinder 12 is a hollow armA 57. One end of this arm is secured to the frame of the machine and its other rear end is positioned within a support 58 V.which extends from a, suitable part of the` frame. A substantially U-shaped arm 59 has one of its ends telescopedwithin the tubular arm 57 and is slidingly adjusted therein, being held in adjusted position by means of a set screw 60. lIhe other end of the arm 59 extends axially withinV the cylinder 12- and carries a baffle plate 61.. This plate is arranged in the path of the stream of air entering the cylinder 12 and acts to separate this stream anddirect it around the inner periphery of the cylinder and retard the passage ofthe grain and straw therethrough under the influence of the air. The'plate may be adjusted toward or away from the entering end of the cylinder and thus regulate the current of air.

The invention is susceptible iof various changes in its form, proportions .and minor details of construction and the right is herein reserved to make such changes as-properly fall within the scope of the appended claims. Having described the invention Vwhat is claimed isz- .Y t
